Thank you Dk, I m XXXX from XXXX,i have my grandma aging 75yrs now, she iz having a severe pain on her knee joints of both legs, the problem has persisted for nearly three years now. She used to be given several drugs (local & hospital drugs) BT unfortunately there is no relief,I one time heard about the efficiency of the diprofos injection,I have been advised to give her 2 doze of injection, one dose and second doze after one week,! So Dk,doing that is right?
